About Cantina
Security is a team sport
We are researchers, operators, and builders closing the loop between finding problems and fixing them — with agents that carry the whole community's expertise into every stack they touch.
- Researchers
- who find the bugs everyone else misses.
- Operators
- who've run security at real scale.
- Builders
- who ship the fix, not the finding.
We close the loop between finding and fixing.
The security industry is exceptional at finding problems and exhausted by fixing them. Scanners, bounties, and pen tests all end the same way — a pile of findings handed to a team that's already underwater.
Cantina exists to finish the job. We build agents that carry an issue from the first signal to a verified, on-record fix — grounded in the playbooks of the researchers and operators who've done this work by hand. Every loop we close makes the next one faster, and every fix stays under your control.
The loop we close
- 01 Discover Surface what's real across code, cloud, identity, and endpoints.
- 02 Prioritize Correlate weak signals down to the few that are real and reachable.
- 03 Fix Carry the issue all the way to a change that ships — not a ticket.
- 04 Verify on record Confirm the fix holds and put it on record.
Built by the people who break things for a living.
Cantina is the sharp end of a much larger group — independent researchers who find the bugs everyone else misses, and operators who've defended real systems at scale. Their playbooks, evals, and detections are what every agent runs on, not a bolt-on.
500+ researchers and operators shape what we build — and share in the upside when their work ships.
A finding nobody fixes isn't security. It's a backlog.
The scoreboard that matters isn't alerts raised or bugs reported — it's loops closed. So we measure ourselves on verified fixes, not raw findings, and we won't call anything "done" until the fix is on record and holding.
close the loop — then close it faster next time
You set the bounds. Agents stay inside them.
Autonomy is a dial you control, set per action and per integration. Agents investigate and draft fixes on their own, but nothing lands outside the limits you set — and the approvals live wherever your team already works.
100% of agent actions are logged, attributable, and reversible — an audit trail anyone can trust.
The principles behind every agent.
-
Community-driven
Every agent carries the playbooks of the researchers who came before it. The community's expertise is the product's foundation, not an afterthought.
-
Agentic by default
Agents do the work end-to-end — triage, investigation, remediation — so your team spends time on judgment calls, not busywork.
-
Verified fixes, not raw findings
We optimize for closed loops. A fix isn't finished until it's proven to hold and written to the record — findings alone don't count.
-
Human-in-the-loop control
Autonomy is set per action and per integration. Approvals live wherever you want them, and nothing acts outside the bounds you set.
-
Transparent by design
Every decision an agent makes leaves an audit trail — reversible, reviewable, and legible to anyone who needs to trust the outcome.
-
Fast where it counts
Speed on the loop, patience on the guardrails. We move quickly to a fix without ever skipping the checks that keep you safe.
A community-scale program, always on.
A handful of operators, backed by a whole community and a workforce of agents — so coverage never sleeps and nothing real slips through.

Built with the community. Backed by people who've done the work.
Cantina is the sharp end of a much larger group. The researchers who break things, the operators who defend at scale, and the investors who've been in the trenches all shape what we build — and keep us honest about what "closed" really means.
A community, not a vendor list
Independent researchers and operators contribute the playbooks, evals, and detections that every agent runs on — and share in the upside when they do.
Backed for the long game
We're funded by investors and operators who've built and defended security programs at scale, and who back founders solving the hard, unglamorous parts.
Trusted by security teams shipping software at scale
Every loop we close makes the next one faster.
That's the compounding advantage of a community behind every agent — and the reason we built Cantina.
